An efficient simultaneous electrochemical detection of nanomolar epinephrine and uric acid using low temperature synthesized nano-sized copper telluride

Herein we developed a simple, cost effective, electrochemical sensor based on nanosized copper telluride (nps-CuTe) for simultaneous detection of epinephrine (EP) and uric acid (UA). Voltammetric responses suggests dramatical improvement of electrocatalytic properties of both molecules by incorporat...
